am maybe sure you are probably right, but have to leave and couldn't wait, so bot a small bit more to keep averaging down. not enough to cry over if it doesn't work out, but enough to be happy about if it does. kind of like 50 cent poker, the game is more interesting if you through your 4 bits in. 'sides, bit support for where its at and not a drop (though only one small, insignificant finger in the dike - guess it depends on how big the hole is). will check in later. luck.
